Review Article: Utilization of Natural Sources of Linoleic Acid in Cosmetic Formulations

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

A user is interested in creating a hair growth serum using oleic acid, palmitoleic acid, and anhydrous ethanol, and seeks advice on sourcing these ingredients. Another user plans to mix these with minoxidil, which already contains ethanol, and mentions using RU58841.

The conversation discusses using sunflower oil as a carrier oil with rosemary oil for hair loss treatment, as it doesn't leave the scalp overly oily like hemp seed oil. The user also mentions avoiding minoxidil due to side effects and using rosemary oil to reduce hair fall and promote new growth.

Saw palmetto's fatty acids, particularly lauric and linoleic acids, inhibit enzymes linked to hair loss, while sterols like beta-sitosterol are less effective due to poor absorption. The conversation questions which specific compounds in saw palmetto contribute to its anti-androgenic effects.
